When comparing Fireworks vs Sketch, the Slant community recommends Sketch for most people. In the question“What are the best mockup and wireframing tools for websites?”Sketch is ranked 4th while Fireworks is ranked 5th. The most important reason people chose Sketch is:

Sketch is hugely popular among designers so there are a lot of well maintained community [resources](http://www.sketchapp.com/community/) for everything from iPhone frames to iOS/Android UI elements & icons.

Pros

Pro

Can be used for the entire life-cycle of the design

From lo-fidelity wireframe, into clickable prototype and then assemble the images for the final hi-fi build as well.

Pro

Layer Sharing

Features such as 'Layer Sharing' allows you to quickly update shared components such as headers across multiple pages. Other mockup tools such as Mockingbird will require you to manually propagate changes across all the pages.

Pro

PSD compatible

Open PSD files

Pro

Awesome Symbol Libraries

A significant advantage over web-app style mockup tools are the symbol libraries for Fireworks.

Both symbols, styles and vector shapes can be saved for re-use and collected into useful library resources. In addition Fireworks ships with a common library of useful objects including buttons, browser and application elements for both Mac and Windows look and feel.

Pro

Active community with a lot of resources

Sketch is hugely popular among designers so there are a lot of well maintained community resources for everything from iPhone frames to iOS/Android UI elements & icons.

Pro

"Artboards" are great for working on multiple views simultaneously

Artboards let you easily work on multiple views side by side. Great for having a separate artboard on each page for the various responsive sizes.

Pro

Vector based yet pixel aware

You can rescale assets without quality loss, easily export x2 assets for retina designs and design high quality icons & artwork. Being pixel aware lets you set a grid and snap objects to it as well as round to the nearest pixel edge to clean up your layers.

Pro

Designed specifically for web and mobile UI design & workflows

Sketch is essentially a version of Photoshop built from the ground up to suit the workflow of web designers.

Pro

Makes it easy to export assets

Sketch has a built in exporter that supports PDF, JPG and PNG.

Pro

Clean UI

Reactive panels keep the UI for Sketch clean from the sort of clutter the panel system in Photoshop suffers from. The panels in Sketch change based on the object in question, saving you from having to have a multiple separate panels.

Pro

Built-in grid system

You can set the square grid to whatever dimensions you like as well as set thicker lines every x blocks. You can also configure the color of the lines to make them as obvious or subtle as you wish and toggle the grid with a keyboard shortcut (crtl+g).

Pro

Symbols and shared styles

Sketch lets you re-use the same design in multiple places, with changes synced throughout the various places it is used. You can also create text styles to sync typography changes.

Pro

"Mirror" makes it really easy to test designs on multiple devices

Mirror lets you connect your iPhone to sketch and see how your current artboard looks on mobile. It's really useful as you can live check changes which lets you rapidly iterate mobile design.

Pro

Easily align layers with smart guides

Holding down alt will show the smart guides that show the distances between any layer you hover over to nearby layers or the edges of the artboard. Very useful for checking your spacing or aligning layers.

Cons

Con

Is being phased out

Adobe is ditching Fireworks. So those nasty bugs will never get fixed.

Con

No Linux version

Sketch is currently only available on Mac, which can make it hard to collaborate if you have teammates using Linux.

Con

License based payment model

Sketch has recently decided to cease development of major version (2.0, 3.0, 4.0) with free updates in between, and has switched to a license based subscription model. A yearly license costs $99 and includes the latest version of the Sketch software, plus a year of free updates. After this license expires, you can renew for another year of updates - or continue to use the current software without updates.

Con

No Windows support

Con

Very feeble raster tools

You have to go elsewhere if you want something more complex than basic vector masking of raster images.

Con

Buggy releases and lack of quality assurance

The fast rate of change means new releases often break files and cause havoc. Duplicate symbols are really bad in the latest releases so you have to keep updating.

Con

Limited compatibility with Photoshop and Illustrator

Although it is possible to export certain Adobe file types in Sketch, compatibility is mostly hit and miss. For example, some elements seem a little offset in Adobe products.
